Global warming is a pressing issue that affects everyone. Though it may be hard to tell right now while we still have polar ice caps, National Geographic recently created a series of maps that illustrate how visually different the Earth would look if all the ice on the planet melted. The maps reveal a world with far fewer land masses that are above sea level. With all the glacial bodies thawing, it would lead to a rise in water levels by 216 feet. As a result, many of the continents’ current coastal areas would be submerged.
